Single-melody pitch detection. Chords and full mixes may need substantial editing.
How to Convert Audio to MIDI
Upload a clear MP3 or WAV with one instrument or voice playing a single melody. Analyze up to 30 seconds, inspect the detected notes, and download a MIDI with Pro. The browser-based detector estimates one pitch at a time; it does not separate a full band into tracks.
Edit the Notes on a Spectrogram
Click a detected note to remove an unwanted event. Click an empty area to add a note at that time and pitch. Use the spectrogram as a guide, then play the notes before exporting.
Free vs Pro Limits
Inspect your audio and download a spectrogram image for free. Pro unlocks MIDI downloads and unlimited WAV exports. This version uses local pitch detection, not a cloud AI transcription service.
FAQ
Does MP3 to MIDI preserve the original sound?
No. MIDI stores note instructions, not audio. Choose an instrument in your music app to play the exported notes.
Can I convert piano chords or a full song?
The current detector is intended for monophonic melodies. Chords, reverb, drums, and overlapping voices can produce missing or incorrect notes.
